"""
Entry point for Hugging Face Spaces deployment.

This file is required by Hugging Face Spaces to run the FastAPI application.
It imports and runs the FastAPI app from 2_backend_llm/app/api.

Hugging Face Spaces will automatically detect this file and run it.
The app will be available on port 7860 (HF Spaces default).
